Charles County officers have arrested two women charged in the roadside deaths of two local men last year.

Rachel Anna Buckler, 21, of Pomfret has been charged with leaving the scene of the hit-and-run accident that resulted in the Sept. 10 death of Port Tobacco cyclist Thomas Mark Roepcke.

Jacquline Vivian Kierre Mack, 21, of Waldorf has been charged with the negligent homicide of Andre Nelson Shorts, 31, of Clinton, who was struck by a car and killed Nov. 12 while walking in a grassy area along westbound Holly Tree Lane in Waldorf.

Both women were indicted and issued bench warrants March 16 after investigators concluded their investigations.

The women’s identities were kept secret and their cases sealed until the warrants had been served.

A passerby found Roepcke, 47, unconscious on the side of Chapel Point Road around 3 a.m. Sept. 2 near its intersection with Taurus Lane in Port Tobacco. A witness told investigators that Roepcke had been cycling south in the area about five hours earlier.

Roepcke was listed in critical condition at a nearby hospital, where he later died.

Police identified Buckler on Sept. 3 as the driver who struck Roepcke but did not release her name, citing the ongoing investigation.

Evidence at the scene indicated Roepcke had been struck by a silver passenger car that was heading north on Chapel Point Road at the time of the accident. Police said the car suffered damage to its driver’s side, including the side-view mirror, headlight assembly and windshield.

Shorts was struck just after 11 a.m. Nov. 12 when Mack, traveling east, lost control of her black Scion and went off the roadway, police said.

Shorts was flown to Prince George’s Hospital Center in Cheverly with life-threatening injuries. He died two days later.

Mack remained at the scene, but police did not release her name at the time.

In addition to negligent homicide, Mack has been charged with vehicular manslaughter, driving under the influence, driving while impaired and driving while her license was suspended, according to online court records.
